In contrast to existing models, that fail for lean hydrogen mixtures, the present model includes the effect of flame instabilities. The model is applied to study the effect of burner geometry on flashback tendency. A diverging geometry results in a higher flashback tendency due to an adverse pressure gradient. These observations are in line with experimental results. It shows that the BLF model is a tool that could significantly contribute to the development of lean premixed hydrogen burners. This is a great step towards carbon-free industrial gas turbines.
